Description

Comprehensive reinforced solar photovoltaic computer cable

technical field

The utility model relates to a comprehensive reinforced solar photovoltaic computer cable structure, which belongs to the field of new cable technologies.

Background technique

Solar energy is the most important basic energy among all kinds of renewable energy. Biomass energy, wind energy, ocean energy, water energy, etc. all come from solar energy. Broadly speaking, solar energy includes the above... Photoelectric conversion devices are usually photovoltaics using semiconductor devices Effect principle for photoelectric conversion, so it is also called solar photovoltaic technology.

Solar technology will become one of the green energy technologies in the future. Solar energy or photovoltaic PV is widely used in China. In addition to the rapid development of government-supported photovoltaic power plants, private investors are also actively building factories and planning to put into production solar modules for global sales. But for now many countries are still in the learning phase. There is no doubt that in order to obtain the best profits, all companies in the industry need to learn from those countries and companies that have many years of experience in solar energy applications. Failure to use dedicated cables for solar applications will affect the service life of the entire system.

Contents of the invention

The purpose of the cable of the utility model is to provide a comprehensive reinforced solar photovoltaic computer cable suitable for this special occasion in view of the deficiency of the traditional cable in terms of resistance to harsh environments.

The utility model comprises four sets of cable cores, and a total shielding layer and an outer protective layer are sequentially arranged outside the four sets of cable cores; a reinforcing steel wire is arranged at the center of the four sets of cable cores, Filling is provided between the layers; each group of cable cores includes two strands of insulated wire cores twisted with each other, and a separate shielding layer is arranged outside the two strands of insulated wire cores, and each of the insulated wire cores includes a conductor. An insulating layer is provided outside the conductor.

The conductor of the utility model is made of oxygen-free copper, and the insulating layer is made of low-smoke and halogen-free cross-linked polyolefin cable material specially used for photovoltaics. When cabled, steel wire is used to strengthen the structure, and the core of the shielded cable is cabled with double-layer copper wire. Shielding, outer sheath extruded photovoltaic low-smoke halogen-free cross-linked polyolefin cable compound. The cable manufacturing process of the utility model is simple and convenient, and the cost is not high. It has the characteristics of high temperature resistance, ozone resistance, ultraviolet resistance, small dielectric loss, strong anti-interference ability, high mechanical strength, good composite utilization effect, and resistance to harsh environments. Widely used in various fields such as security engineering, fire protection engineering, monitoring engineering, solar power plants, and photovoltaic systems.
